MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 237,702, dated February1,5, 1881.

Application filed January 10, 1881. (No model.)

To all whom it may concern:

Be it known that I, GEORGE S. ROMINGER, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented a new MechanicalMovement, of which the following is a specification.

My invention consists of an improved mechanical movement, which is toofully described hereinafter to need preliminary explanation, and theobject of which is to convert a rotary into a vibrating motion by apeculiar construction and combination of parts. which insure thedurability and accurate working of the operating elements ofthe device.

1n the accompanying drawings, Figure 1 is a side view of my improvedmovement; Fig. 2, a sectional plan on the line 1 2; Fig. 3, an end view,partly in section, and looking in the direction of the arrow, Fig. l;and Fig. 4, a diagram illustrating my invention.

`A is a drivingshaft adapted to fixed bearings, and B the shaft to whicha vibrating motion has to be imparted, the axis w of this shaft being atright angles to and passing through the axis y of the diivingshaft. Tothis shaft A is secured a collar, D, in which is cnt an oblique groove,a. The relation of this groove and the center lines or axes of the twoshafts to each other will be best observed on reference to the diagram,Fig. 4, in which the point x represents the axis of the shaftD in thecentral line, y, of the driving-shaft A.

If an oblique line, m m, be drawn through the center, x, the edges n nof the groove in the collar should be on opposite sides of andequidistant from this line. The bottom p of the groove should preferablybe at right angles to the line, and the points pp, where the line m mcrosses the bottom of the groove, should always be equidistant from thepojntw.

The shaft B is adapted to a fixed bearing or bearings, b, and the upperend of this shaft is forked, s0 as to present two arms, cl d', into eachof which is screwed a stud, e, Fig. 3, the two studs fitting in orificesin a collar or sleeve, Gr, which is fitted snugly in the groove of thecollar I), said sleeve being made in two parts for introduction into thegroove.

When the driving-shaft is turned a vibrating motion must necessarily beimparted to the shaft B, and the movement thus obtained may be appliedto the driving ofthe shuttle of a sewing-machine, or to thereciprocating of a slide-valve, or to the imparting of a vibrating orreciprocating movement to any object.

It will be seen that the device partakes somewhat of the character ofthe well-known movement in which a grooved cam on a shaft reciprocatesan arm but it differs from such movements in this respect, that thepower is transmitted from the driving-shaft through uniform and extendedbearing-surfaces, by which durability and freedom from rattling noisesare attained, and that in reaching this result I have departed, inarrangement and construction of parts, from the usual grooved camdevices, especially in using the sleeve Gr, by which uniform bearingsurfaces are attained.

I claim as my invention- A mechanical movement in which a drivingshafthaving an oblique groove or a collar with au oblique groove is combinedwith a shaft whose axis is at right angles to and passes through that ofthe driving-shaft, and with a sleeve adapted to the said groove andstuds carried by the shaft B and adapted to orifices in the sleeve, allsubstantially as set forth.

ln testimony whereofIhave signed myname to this specification inthepresence of two subscribing Witnesses.

GEO. S. ROMINGER.
